ports 13 are formed through the cap memher 8 and are normally closed when the engne 1s 1dle by means of the valve or washer From the foregoing descriptionit will be apparent that when the internal combustion engine is started, the suction inrthe intake manifold will draw the valve or washer 12 down against the spring member 11, so that the ports 13 will be uncovered and the ail will be drawn therethrough and over the chemical, and through the passages 7 and 6 and in through the intake manifold to the interior'of the engine 3, where the chemicalized air will cut and clean the carbon deposits. It will be noted that the valve or washer 12 is slightly smaller in diameter than the inner diameter of the housing 4,

thereby making it possible for the air to be drawn around the same as it passes over the chemical and into the engine. v

It will be readily understood that the tension on the spring member ll may be adjusted, as desired, by simply turning up or down on the threaded stem 9. If perchance the spring member 11 should become broken o'r-in any manner injured, the new member may readily be placed-in position by removing the screw 15 and replacing the new member.

Owing to the self-closing air admission valve being located in advance of the chemical element in the mixing chamber instead of between the chemical element and the.

My improved attachment may also be ap-' plied to the mixing chamber in a carbureter with equally good results;

Many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

For exam Ie, the air valve need not be self-closing but may be closed or adjusted by hand, and the valve need not bewholly closed when the motor is idle, but merely closed to an extent necessary ,to prevent ap preciable vaporization and -waste of the chemical.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is 1. In combination, a hollow cylindrical chamber adapted to contain a chemical element, of means at the outer end of the chamber adapted to admit air over the chemical element, the said means comprising a removable threaded cap member, which is providqd at its center portion with a threaded stem, and carries on its lnnei end a reabl w i g m m r, and e lM m mber d posed between the spring and the cap wiereby the valve element maybe adjnstably tensioned against the under surface the cap member.
